Hello,
There have been a number of SDOs and other groups that were requiring object-oriented constructs in YANG. However we were out-voted.

Myself I am trying to map 3GPP objects to YANG (3gpp TS 32.160 section 6.2 https://www.3gpp.org/ftp/Specs/archive/32_series/32.160/32160-h30.zip).  I am trying to find a balance between mimicking object-orientation and keeping YANG readable. It is not always easy. 

I know that there are similar efforts in ITU and other organizations. Scott may have a full list of such efforts.
Regards Balazs

RFC6095 might be a starting point for that sort of work. I am not sure anybody ever implement that, though.
